Description

Suspension type LCD support frame

Technical Field

The utility model relates to the technical field of display screen supporting frames, in particular to a hanging type liquid crystal display screen supporting frame.

Background

The so-called LED lcd is not an exact term, but is simply an abbreviation added to it for the sake of convenience to the media and the networker. It should be referred to as an LED backlight liquid crystal display. According to the principle of the liquid crystal display, the liquid crystal display is characterized in that liquid crystal molecules refract light rays of a backlight source to display different colors, and the liquid crystal molecules cannot emit light, so that the liquid crystal display is mainly realized through illumination of the backlight source. Most backlights for liquid crystal displays are CCFLs (also known as cold cathode ray tubes), whose principle is similar to that of our fluorescent tubes. The LED backlight is a novel backlight source for replacing CCFL, and the existing patent with publication number CN214037492U, for example, is a hanging structure for LED display screen, which solves the problem that the elevation angle of the display can not be adjusted when in use, and the elevation angle of the display can not be adjusted to be rotated downwards, and the height and the left and right directions of the display can not be adjusted, thus affecting the practicality.
